球墨铸铁断裂韧度测试技术研究进展
Research Progress on Fracture Toughness Testing Technology of Ductile Cast Iron
摘 要
断裂韧度是材料重要的抗断指标。总结了平面应变断裂韧度、弹塑性断裂韧度、裂纹尖端张开位移和动态断裂韧度测试技术的研究概况及在球墨铸铁材料上的应用，介绍了温度、显微组织、试样尺寸对球墨铸铁断裂韧度的影响规律，探讨了球墨铸铁断裂韧度试样中的裂纹长度测试问题，介绍了基于J-Q（J积分-三轴性应力因子）理论的球墨铸铁断裂韧度测试方法；认为基于J-Q理论的多参数断裂韧度测试是未来研究的重点，并且若要使断裂韧度真正用于工程安全评定，必须在测试时综合考虑实际服役时的加载模式及环境。

Abstract
Fracture toughness is an important fracture resistance index of materials. The research status of plane strain fracture toughness, elastoplastic fracture toughness, crack tip opening displacement and dynamic fracture toughness testing techniques and their application to ductile cast iron materials are summarized. The influence of the temperature, microstructure and sample size on the fracture toughness of ductile cast iron is described. The problem of crack length testing in the fracture toughness specimen of ductile cast iron is discussed. The test method of fracture toughness of ductile cast iron based on J-Q (J integral-triaxial stress factor) theory is also described. It is believed that the multi-parameter fracture toughness testing based on the J-Q theory is the focus of future research. Furthermore, if the fracture toughness is to be used for engineering safety assessment, the loading mode and environment in actual service must be comprehensively considered during the testing.
